Being homeless and receiving this benefit does not come without some expectation.  To help better the society that the homeless have come from, an opportunity will be created to help improve these areas.  The homeless will help to keep the streets clean and aid disabled or low income individuals by providing basic needed services.  Many homeless people live in depressed neighborhoods where the population is older or less affluent and that need help to improve the environment.  These improvements can come in the form of a coat of paint, cleaning the street or cutting the grass or trimming trees.  By doing this, you can improve the overall environment for all involved including the homeless.  It will also give them a sense of accomplishment and would be a good way for them to give back for the benefit they have received.
